  • Fact: Dead Sea Facts

    Despite it’s name the Dead Sea which is located between the borders of Israel and Jordan is actually a lake. Sitting in a valley almost 400m below sea level it’s positioned at not only the lowest point on Earth but also happens to be the second saltiest lake in the world (1st saltiest being lake Assal in Djibouti, Africa).

    In fact it’s so salty (almost 8 times saltier than regular sea water) that nothing except small plants and salt loving bacteria survive, explaining why it’s called the Dead Sea i.e. nothing in it survives.

    Salt Makes You Float ?

    Now despite very few things being able to survive one cool thing about the lake is that most things that enter it float. It’s a feature well publicized in both pictures and videos of tourists visiting the lake for it’s health & spa benefits.

    The basic theory behind the floating is that salt water is much denser than regular water and it’s this density which makes the water much more buoyant. If you want to float on your back completely unaided whilst reading the newspaper, well that’s not a problem in the Dead Sea because it’s extremely salty!

    The Dead Sea is Dieing

    Unfortunately due to it’s climatic position almost 7 million tons of water evaporate from the lake every day. In addition to that both Israel and Jordan are tapping into the Jordan river (the Dead Sea’s main water source) for irrigation purposes at a rate which is depleting the lake to dangerous levels.

    Combine that further with the recent droughts we’re seeing in the region and it’s quite clear that the famous lake is drying up with many parts already below the point of recovery.

  • Fact: Birds That Can Talk

    Did you know that parrots can be trained to say up to 200 words and short phrases. In fact their ability to mimic human language is so well known that many parrot owners initially purchase the bird for this reason alone.

    The truth however is that like most talking birds they’re not really talking but mimicking the sounds they hear around them. They certainly don’t have any real understanding of the words they repeat and what’s more interesting is that parrots as a species are not the best of the bird mimickers.

    Mynah Bird

    Yes that’s right the top word mimic is actually the Mynah bird. Their ability to create amazingly realistic human and non human sounds such as words, coughs, sneezes and even cell phone ring tones is well documented.

    Other birds that are extremely intelligent and known to mimic human words are crows, ravens and jackdaws. Although their abilities are less publicized.
